I got two PDFs ebooks sent from a friend and I noticed when I clicked on the file and preview opened it up on OSX 10.8.2 Littlesnitch alerted me that Finder was attempting to connect to "wallet.google.com" I blocked it and scanned the files using "Virustotal.com" which turned up negative. I've never had any attempt to connect to wallet.google.com so I'm a little suspicious.

I also recently installed Java 6 for necessary software so I'm kind of afraid I might be vulnerable.

Does anyone know if OS X is vulnerable to virus laden PDF? Should I reinstall to ensure system security?
